He says he was contacted that day by someone who told him there had been an incident at this event similar to what is alleged to have taken place at a Young Labour summer camp in February.

Mr Kirton says he's currently working with the person who made the complaint, and has encouraged them to go to the police if they want to.

He refused to disclose the location and date of the event, saying the omission was out of respect for the people involved. He does not believe the alleged incident involves Labour Party MPs or Ministers.

The party is currently facing criticism over its handling of alleged sexual misconduct at a Young Labour Summer Camp in February.

Four 16-year-olds were allegedly harassed or assaulted by a 20-year-old man at the camp in Waihi.

Labour did not inform the police, the Prime Minister or the alleged victims' parents about the incidents.

Mr Kirton says while they had the interests of the young people at heart, he admits they handled the situation poorly.
